Like its predecessors, the Huey II's main rotor drive shaft has a 5° forward lean, and so the fuselage stays nicely level during the cruise. Rotor RPM (NR) is a low 324.

An incident in April resulted in “significant damage” to a TH-1H’s “nose, cabin, mast, and main rotor head and tail rotor assemblies.” So, pretty much the entire helicopter.
